Colour temperature black body radiation
WebJan 18, 2024 · The colour temperature is defined as the temperature of an ideal black body that radiates light of that colour. Unfortunately most objects are not ideal black body radiators so there is no direct comparison. For example, LED lights do not emit light by thermal radiation, as such the colour of the light is not determined by the temperature.

WebOct 20, 2024 · It is called the color temperature of the light source. In black body radiation , with different temperatures, the color of light varies, and the black body presents a gradual process from red to orange red to yellow to yellow white to white to blue and white. When the color of light emitted by a light source looks the same as the light … WebFig 2: Black body radiation curves showing peak wavelengths at various temperatures This graph shows how the black body radiation curves change at various temperatures. These all have their peak wavelengths in the infra-red part of the spectrum as they are at a lower temperature than the previous graph. The graph shows:.
